DEVICE FOR RAISING CARRIAGE AND OTHER WINDOWS.

Application filed September 25, 1923. Serial No. 684,760.

have invented a new and useful Device for Raising Carriage and Other 'Windows, of

which the following is a specification.

My invention relates to a device for lift 'ing carriage and other windows and to hold them up at any desired height, this operation being effected by two knee jointed arms one of which describes a circle while the other is actuated by suitable epicycloidal gear for transferring to the end of the latter arm the lineal displacement required for the manipulation of the window.

Suitable controlling mechanism is provided for facilitating the operation while 3 locking means are designed to linnt the same.

Fig. 1 is a side elevation of the apparatus.

Fig. 2 is a side elevation partly in section online MN of Fig. 1.

Fig. 3 is a plan view partly in cross sec-- tion on line KL of Fig. 1.

In the drawings, 1 is a carriage or other door window hollow at 2 to receive the window pane 3, 4 being the lower part of the window frame and 5 a support having a clamp 67 furnished with a spring 8 rocking upon the axis 9-10 and holding the connecting rod knob of the device. A hook 11'with an india rubber fitting 12 is con-' veniently arranged to deaden the vibrations .and noise of the pane 3.

A connecting rod 13 is jointed by its knob 14 and'the 'clamp 67 to the bottom of'the window pane 3 and in turn driven by a pinion 15 mounted upon the axis 16 held by the main arm 17; the latter has the shape of a stamped gear case turning upon an axis 18 connecting the lid or cover 19 with the fitting cross piece 20.

I This arm is moreover provided with a star 45 wheel 22 keyed on the axis 21 and meshing with the pinion 15 which rolls upon the central wheel 23, with a crown plate or piece provided with inner teeth'imparting a motion to the main arm 17, and with rollers 25 in contact with a compensating lever 26.

The central wheel 23 is fixed to the lid or cover 19 by tic-rods and is provided with a groove 28 for the passage of the rollers 25. The compensating lever 26 rocks at 29, its end 30 being in contact with the main arm rollers 25 ,while its'other end 31 is constantly held under the action of a spring 32 to break the shifting of the main-arn'i and thus prevent a sudden fall of the window frame.

The controlling device comprises a pinion 33 meshlng wlth the crown piece 24 and carrying upon its axis a wheel 35 meshing with the driving pinion carrying upon its axis 37 a handle 38. The latter has a knob 39 carried by a lever 40 fulcrume-d at 41 and pressed by a s ring 42 being'further fur nished with a eak 43 to engage with the toothed wheel 44 of a hollow support 45 surrounding the axis 37 and fixed upon the box 46 of the controlling device.

The knob 39 pushed by the spring 42 enters the handle 38 to avoid any part of, the wearing apparel of any one being hooked on, its leverv 40 with its beak 43 and the toothed wheel 34 forming a self locking device operating as soon as the handling operation is over and the knob released.

The arm 13 may be rovided on its side with any desired hooking device allowing for a drop, so as to be able to lift the glass with or without such drop.

As shown, the movements are imparted by a knee jointed elbow the main arm 17 of which receives its motion from the main gear and imparts it to the device, its secondary arm or connecting rod is actuated by epicycloidal gear with suitable connections for imparting to the end P of the said connecting rod 13 the linealdisplacement necessary for the working of the window.

The device can be rapidly and readily put in its place by fixing the cross piece 20 to the door frame, its travel being regu lated-according to the height of the window frameso as.not to interfere with the carriage or other door. The device is mounted from A to B and its manipulation is effected in the following manner: I

By imparting a circular motion to the handle 38 the pinion 33 sets the crown piece 24 in motion and with it the main shaft 17 which turns about the centre of the device.

The star wheel imparts to the connecting rod or secondary arm a circular motion which causes its end P to pass constantly through the middle line N--M.

' It will be apparent from the above that on turning the shaft 37 by means of the handle, the gear 33 will be operated and thereby the crown 24 will be revolved. The arm 17 is thus swung about the center '18. In the movement of this arm however, the

gear 22, which is in engagement with the fixed gear 23, is turned on its axis 521, with the effect to correspondingly turn gear 15 on its axis 16. As the rod 13 is part of or connected to the gear 15, it will be apparent that the rod 13 is swung about the center 16 as the arm 17 is swung about the center 18. Thus the end of the rod 13 connected to the window is caused to move up or down in a straight line.

I claim:

A device for raising carriage and other windows and allowing them to be held up at any given height, comprising a connecting rod or secondary arm jointed to the window pane armand to the main arm; a main arm turning about the centre of the device carrying a star pinion mounted upon the connecting rod axis and gearing with a sprocket pinion which rolls over a central fixed wheel; a crown piece-having inner teeth actuated by a controlling mechanism provided with a handle and a roller bearing upon a compensating lever; a central toothed wheel over which rolls the sprocket pinion aforesaid and which is furnished with a groove for the passage of the main arm roller; :1 spring compensating lever to contact with the main arm roller and prevent the sudden dropping of the window; and means for operating the main arm toothed wheel.

In testimony whereof I afiix my signature.

ALBERT COUSINARD.
